Find the words and 2, 3 and 4-word phrases you repeat most, with counts and percentages, and filter out common words so the real keywords stand out.
Keyword density is how often a word appears compared with the total number of words. Paste an article, a product page or an essay and this checker lists the 15 words you use most, with the number of times each appears and its share of all the words. Common words such as "the", "and" and "of" are ignored by default so the topic words stand out; untick the box to include them.
It also finds repeated phrases of two, three and four words, which helps you spot a keyword phrase used too often or a habit phrase you keep reaching for. Words are compared in lower case and punctuation is ignored. The analysis runs in your browser as you type.
There is no fixed target. Write for readers first: if one keyword is far above the rest, say over 3 to 4 percent of all words, the text may read as repetitive.
A phrase's percentage is its count divided by the total number of phrases of that length in the text. Only phrases that appear at least twice are listed.
